ALEXANDER WINTON, OF CLEVELAND, OHIO.

SPEED-REGULATOR FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 626,121, dated May 30, 1899. Application filed July 27,1898. Serial No. 687,021. (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER WINTON, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Oil Valves or Feeders for Gasolene- Engines, of which the following is a specification.

My invention relates to improvements in oil valves or feeders for gasolene-engines, and pertains to that class of engines in which a quantity of gasolene and air are drawn together within the explosive-chamber and exploded.

The object ofmy present invention is to provide a specially-constructed spring connection for operating the gasolene-valve, whereby it has a yielding seating action'to insure its tight fit, while at the same time it is given a positive opening and closing movement, the parts also being constructed to permit of adjustment for taking up thewear of the valve and its seat and to prevent noise.

In the accompanying drawings, Figure l is a sectional view of the explosive end of a gasolene-engine cylinder, showing my invention applied thereto. Fig. 2 is a detail view of the adjusting-bolt. Fig. 3 are views of the clamping-nut.

Reference being had to the drawings, A is the explosive end of a cylinder, and projecting rearward from this end of the cylinder is a chamber B, the said chamber having an open inner end in communication with the cylinder and provided with an opening 0 for the explosive mixture.

The explosive-inlet valve K is provided with a valve-stem 70, passing longitudinally through the chamber or cylinder B, the outer end of the stem being provided with a piston H within said cylinder, and communicating with this cylinder to cause a pressure upon the said piston H is a pressure-supplypipe t'. Pressure is supplied to this pipe through the medium of a pressu re-supplying pump, which is actuated by the engine in any desired manner.

In operation the pump supplies pressure to the cylinder, which causes an outward pressure against the piston, which holds the explosive-inlet valve K to its seat with more or less force, according to the pressure upon the I piston, which is varied according to the speed of the engine, and consequently the speed of the pump, as will be readily understood. A spring at is provided for normally holding the explosive-inlet valve to its seat and the parts in their normal operative position.

My present improvement relates particularly to a valve for admitting a predetermined amount of hydrocarbon fluid, such as gaso- -lene, at every other stroke of the engine-piston, which is the usual operation of explosiveengines.

. The gasolene-tank 2 is supported at any desired point, and a supply-pipe 3 extends therefrom into a mixing-pipe 4. This mixing-pipe iis provided with an opening 5,which communicates with the explosive end of the cylinder at a point outside of the inlet-valve. When the piston moves outward, the valve K is opened by suction and the hydrocarbonvalve J,whioh is preferably of the well-known needle or pointed construction, is moved from its seat 6, thus admitting a small quantity of fluid within the pipe 3, which is drawn into the explosive end of the cylinder, together with air that is mixed therewith, and preferably through a carbureter 7. (Shown in dotted lines in Fig. 1 This carbureter may be of any desired form without affecting in any manner my present invention. The hydrocarbon-valve J is connected with the end of the stem of the valve K through themedium of a nut G, which clamps it into position, the said nut in turn being clamped by means of a bolt G. A spring I (preferably of U shape in form, as shown in Fig. 2) has one end clamped to=the stem of the valve K, while its opposite end is connected with the hydrocarbon-valve J, and the spring, being of the expanding form, normally forces the valve J against its seat. The movement of the spring, however, is regulated through the medium of a regulatingbolt H, which has one end screwed into a lug upon the nut G and its 0pposite end provided with an elongated opening f, through which one end of the spring I passes, as also clearly illustratedin Fig. 2. This opening in the rod H allows just enough backward motion of the spring to'accomplish a tight seating of the valve J, while at the same time the rod H forms a positive pull upon the valve for. removing it from its seat through the medium of the stem of the inletvalve K. This construction enables me to use a strong spring I, thereby making the tight closing of the valve more sure, and yet enables me to secure a positive movement of the valve, both of which are very desirable. By means of the adjustable feature the valve may be adjusted for the purpose of taking up the wear of either the valve or of its seat. It will be thus seen that a positive connection is provided for withdrawing the valve from its seat, and practically a positive, and yet a yielding, connection is provided forseating the valve. This construction in use upon a motor-vehicle has been found to produce a most satisfactory arrangement, one which is very sensitive, durable, and not liable to get out of order, in that it automaticallyprovides for the tight seat-in g of the valve and a small wear thereof.

It is also desirable in motors for vehicles to make them as noiseless as possible, and to avoid the clicking noise caused by the seat-. ing of the oil-valve and also the explosive-inlet valve K,I provide a dash-pot or air-cushion situated between the two. This is provided by having the cylinder or chamber 13 extend beyond the piston II to form a space M. The extremity of this cylinder is closed by a cap N, and this cap is provided with a passage or passages P. Through the medium of this arrangement an air-cushion is provided at the outer side of the piston, as will be readily understood, whereby when the valves are being seated they are prevented from a sudden contact with their seats, which avoids the click? ing noise common to mechanisms of this character, and yet it permits a firm and tight seating of both of the valves. It will be noted that this air-cushion, situated, as here shown, between the explosive-inlet valve and the oilvalve, serves a double function in that it regulates the seating of both valves, thus preventing wear upon the valve-seat and also, as before stated,pre"enting the undesirable constant clicking which would otherwise occur.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
